Unspun Ringside With Paul Beckwith, Climate Researcher, At COP21 - Paris

Paul Beckwith, engineer, physicist, climate researcher, talks with us from COP21 Climate Summit in Paris.  He has been reporting back on his blog: http://paulbeckwith.net, where you can find over a hundred videos he has made on abrupt Climate Change.  He also teaches Climatology at the University of Ottawa, where approx. 25,000 people marched last week for climate justice and meaningful action.  He talks to the issues of carbon emissions, CO2 removal and solar radiation management.   Will COP21 be meaningful in anyway?  Can we stop runaway climate change?  What are the factors?
